Efflock's HYDROPHOBIC SEALER FOR MASONRY is another high performance concentrate that dilutes 9 times with water.
This sealer provides genuine long-lasting invisible water repellency to protect porous masonry from waterborne contaminants such as algae, dirt and salt attack. This product will also reduce, or even solve existing efflorescence problems by reducing water from being absorbed into a masonry system. (Refer to page 10 of our Technical Data Sheet
for more information).
Lasts up to 10 years on pavements, and 15 years on walls.
